/*
    This spell creates a gust of wind in all directions
    around the target. All targets in a medium area will be
    affected:
    - Target must make a For save vs. spell DC or be
      knocked down for 3 rounds
    - plays a wind sound
    - if an area of effect object is within the area
    it is dispelled
